SUMMARY
The discussion focuses on the optimal hysteresis loop shapes required for magnetic materials used in permanent magnets and transformer cores. For permanent magnets, a loop with a high coercivity and remanence is essential, ensuring that the magnetic field remains stable without returning to zero when the applied magnetic field (H) is removed. In contrast, transformer cores require a loop that minimizes energy loss, characterized by a smaller area under the B-H curve, allowing for efficient magnetic flux without significant hysteresis losses.
